In addition, in other embodiments, the digitizer tablet 11 may also include a wired communication interface, so that the digitizer tablet 11 and the cloud server 12 can perform wired communications. The microphone of the digitizer tablet 11 can convert a voice signal of a user into an electrical signal, the processor transmits the electrical signal to the cloud server 12 through the wireless communicating module, and the cloud server 12 processes the electrical signal and transmits a processing result to the digitized tablet 11, the processor of the digitizer tablet 11 plays the processing result through the audio outputting module. Specifically, an intelligent voice interaction can be performed between the user and the digitizer tablet 11. When collecting a voice signal of the user, the digitizer tablet 11 converts the voice signal into an audio signal, and transmits the audio signal to the cloud server 12, where the cloud server 12 provides an audio service for the user according to the audio signal, for example, answering a user's question or acquiring multimedia data that matches the user's needs, and transmitting the answer to the question asked by the user to the digitizer tablet 11, or transmitting the multimedia data required by the user to the digital device 11, such that the digitized tablet 11 plays the answer to the question asked by the user, or plays the multimedia data required by the user.

The present disclosure provides an intelligent voice interaction method that aims to solve the above technical problems in prior art.

The technical solution of the present disclosure and how the technical solution of the present disclosure solves the above technical problems will be described in detail below with reference to specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present disclosure will be described below with reference to the accompanying drawings.

FIG. 3 is a flowchart of an intelligent voice interaction method according to an embodiment of the present disclosure. The embodiment of the present disclosure provides the intelligent voice interaction method for solving the above technical problem in the prior art. Specific steps of the method are as follows:

Step 301: obtaining text information or drawing information input by a user on a digitizer tablet.

In the embodiment, the digitizer tablet 11 further includes a pressure sensitive pen through which the user can practice calligraphy or drawing on the digitizer tablet 11. The digitizer tablet 11 can transmit information input by the user on the digitizer tablet 11 to the cloud server 12 in real time. For example, the digitizer tablet 11 may transmit dot matrix data of each stroke of a character or a drawing that is input by the user on the digitizer tablet to the cloud server 12.

Step 302: identifying the text information or the drawing information to obtain an identification result.

After receiving the dot matrix data of each stroke that is transmitted by the digitizer tablet 11, the cloud server 12 can identify the character or the drawing input by the user on the digitizer tablet 11, for example, to identify whether a stroke order of the character written by the user is correct., whether the character written by the user is formal or standard as a whole, or to identify an object drawn by the user.

Step 303: transmitting audio information corresponding to the identification result to the digitizer tablet, enabling the digitizer tablet to play the audio information.

After identifying the character or the drawing input by the user on the digitizer tablet 11, the cloud server transmits audio information corresponding to a respective identification result to the digitizer tablet 11. For example, the cloud server 12 identifies that the stroke order of the character written by the user is correct, however, the character written by the user has a certain difference compared to a standard character, and then the cloud server 12 transmits audio information of “the stroke order is correct, the character as a whole has a certain difference compared to the standard character” to the digitizer tablet 11, so that the digitizer tablet 11 plays the audio information.

According to the embodiment of the present disclosure, a digitized tablet collects text information or drawing information input by a user, and transmits the text information or the drawing information to a cloud server, where the cloud server identifies the text information or the drawing information and transmits audio information corresponding to an identification result to the digitizer tablet, so that the digitizer tablet plays the audio information, in this way, the digitizer tablet performs an intelligent voice interaction with the user according to the text information or the drawing information input by the user when the user practices calligraphy or drawing, thereby increasing an interactivity between the user, especially a child, with the digitizer tablet, and enhancing the child's interest in learning.

FIG. 4 is a flowchart of an intelligent voice interaction method according to another embodiment of the present disclosure. On the basis of the foregoing embodiment, the intelligent voice interaction method provided in this embodiment specifically includes the following steps:

Step 401: receiving dot matrix data of each stroke of a character and dot matrix data of the character as a whole written by the user on the digitizer tablet.

As shown in FIG. 5, for example, the character input by the user on the digitizer tablet 11 is a character of “

”, and the digitizer tablet 11 transmits dot matrix data of a stroke to the cloud server 12 each time the stroke is written down by the user. It can be understood that when the user is writing the same stroke, a movement track of the pressure sensitive pen on the electronic ink screen of the digitizer tablet 11 is continuous, or a movement track of a cursor of the digitizer tablet 11 on the electronic ink screen is continuous. When different strokes are written by the user, the movement track of the pressure sensitive pen or the cursor on the electronic ink screen is discontinuous. For example, strokes of the character of “

” includes a “horizontal stroke (

)”, a “left-falling stroke (

)” and a “right-falling stroke (

)”, when the user writes the “horizontal stroke (

)”, a movement track of the pressure sensitive pen or the cursor on the electronic ink screen is continuous, and as the user writing the “left-falling stroke (

)”, the movement track of the pressure sensitive pen or the cursor on the electronic ink screen will be interrupted. Correspondingly, the digitizer tablet 11 can identify a stroke input by the user on the digitizer tablet 11 according to a movement track of the pressure sensitive pen or the cursor on the electronic ink screen. Alternatively, basic strokes of Chinese characters may be stored in the digitizer tablet 11. There are eight basic strokes of traditional Chinese characters, namely, “a dot stroke (

), a horizontal stroke (

), a vertical stroke (

) a left-falling stroke (

), a right-falling stroke (

), a turning stroke (

), a curve stroke (

)and a hook stroke (

)”, the digitizer tablet 11 can identify the user's input on the digitizer tablet 11 according to the movement track of the pressure sensitive pen or the cursor on the electronic ink screen, and the basic strokes of the Chinese characters.

Each time a stroke is identified by the digitizer tablet 11, the digitizer tablet 11 transmits the dot matrix data of the stroke to the cloud server 12, and also transmits dot matrix data of the entire character (the character as a whole) such as “

” to the cloud server 12. As shown in FIG. 5, the digitizer tablet 11 sequentially transmits dot matrix data of the “horizontal stroke (

)”, dot matrix data of the “left-falling stroke (

)”, dot matrix data of the “right-falling stroke (

)”,and dot matrix data of the entire character “

” composed by a “horizontal stroke (

)”, a “left-falling stroke (

)” and a “right-falling stroke (

)” to the cloud server 12.

Alternatively, each time a stroke is identified by the digitizer tablet 11, the digitizer tablet 11 transmits dot matrix data of the stroke and dot matrix data of strokes that are previously identified to the cloud server 12, and also transmits dot matrix data of an entire character such as “

” to the cloud server 12. As shown in FIG. 6, the digitizer tablet 11 sequentially transmits dot matrix data of a “horizontal stroke (

)”, dot matrix data of a “horizontal stroke (

)” and a “left-falling stroke (

)”, and dot matrix data of the entire character “

” composed by a “horizontal stroke (

)”, a “left-falling stroke (

)” and a “right-falling stroke (

)” to the cloud server 12.

Step 402: determining whether a stroke order of the character written by the user is correct according to the dot matrix data of each stroke of the character written by the user on the digitizer tablet that is transmitted by the digitizer tablet.

For example, the cloud server 12 determines whether a stroke order of the character “

” written by the user is correct according to the dot matrix data of the “horizontal stroke (

)”, the dot matrix data of the “left-falling stroke (

)” and the dot matrix data of the “right-falling stroke (

)” transmitted by the digitized tablet 11 sequentially.

In an embodiment, the determining whether a stroke order of the character written by the user is correct according to the dot matrix data of each stroke of the character written by the user on the digitizer tablet that is transmitted by the digitizer tablet includes: determining an image corresponding to each stroke of the character according to the dot matrix data of each stroke of the character; and comparing the image corresponding to each stroke of the character with a standard stroke image of the character to determine whether the stroke order of the character written by the user is correct.

For example, the cloud server 12 determines an image corresponding to the “horizontal stroke (

)”, an image corresponding to the “left-falling stroke (

)” and an image corresponding to the “right-falling stroke (

)” according to the dot matrix data of the “horizontal stroke (

)”, the dot matrix data of the “left-falling stroke (

)” and the dot matrix data of the “right-falling stroke (

)” transmitted by the digitized tablet 11 sequentially. In an embodiment, the cloud server 12 includes a text database, where the text database includes data such as a writing method, a stroke order, a writing method of regular script, a word meaning, a sentence, and the like of more than 20,000 Chinese characters and simple English. The cloud server 12 determines whether a stroke order of the character, for example, “

”, written by the user is correct by comparing an image corresponding to each stroke written by the user with the a standard stroke image of the character of “

”.

Step 403: determining whether the character written by the user is standard according to the dot matrix data of the character as a whole.

For example, the cloud server 12 identifies a character written by the user according to the dot matrix data of the entire character “

” transmitted by the digitizer tablet 11. In an embodiment, the identification may be performed by using an optical character recognition (OCR) algorithm. For example, the cloud server 12 identifies that the character written by the user is a character of “

”.

Alternatively, the cloud server 12 may also transmit the dot matrix data of the entire character of “

” to another third-party server, so that the third-party server uses the OCR algorithm to identify the character written by the user. For example, the third-party server identifies that the character written by the user is “

”, and the cloud server 12 further determines whether the character of “

” written by the user is standard, for example, by comparing the character of “

” written by the user with the character of “

” in regular script.

In an embodiment, the determining whether the character written by the user is standard according to the dot matrix data of the character as a whole includes: determining an image corresponding to the character according to the dot matrix data of the character as a whole; and comparing the image corresponding to the character and a standard image of the character to determine whether the character written by the user is standard.

As shown in FIG. 7, the cloud server 12 determines an image 71 corresponding to the character of “

” according to dot matrix data of the character of “

” as a whole, and further binarizes the image 71, for example, sets a pixel value corresponding to the character of “

” to be 1, a pixel value corresponding to background to be 0 to obtain a binarized image, and the binarized image is further trimmed on edges (edge trimming) to obtain a cropped image 72. Further, the image 72 and the standard image of the character of “

”, for example, a regular script image 73, are compared. Specifically, difference values between pixel points of the same positions in the image 72 and the image 73 can be compared. Thus, it can be determined whether the character of “

” written by the user is standard. Alternatively, the image 72 and the image 73 are of the same size. If the image 72 that is obtained by edge trimming the image 71 is different in size from the image 73, the size of the image 72 can be scaled accordingly so that the sizes of the image 72 and the image 73 are the same.

Step 404: transmitting audio information corresponding to the identification result to the digitizer tablet, enabling the digitizer tablet to play the audio information.

As shown in FIG. 5 or 6, the cloud server 12 determines that the stroke order of the character of “

” written by the user is correct, but as shown in FIG. 7, the character of “

” written by the user is not standard enough. The cloud server 12 transmits corresponding audio information to the digitizer tablet 11, and the digitizer tablet 11 plays the audio information. For example, the digitizer tablet 11 plays: “The one you wrote is a character of ‘

’, the stroke order is correct, but the script is not beautiful enough, it needs to be strong and powerful.” After hearing the audio information played by the digitizer tablet 11, the user further modifies and adjusts the writing script to write a beautiful character of “

”.

According to the embodiment of the present disclosure, a digitized tablet collects text information input by a user, and transmits the text information to a cloud server, where the cloud server identifies the text information to identify whether a stroke order written by the user is correct and whether the written script is standard, and transmits audio information corresponding to an identification result to the digitizer tablet, so that the digitizer tablet plays the audio information, in this way, the digitizer tablet performs an intelligent voice interaction with the user according to the text information input by the user when the user practices calligraphy, increasing the writing scripts.

FIG. 8 is a flowchart of an intelligent voice interaction method according to another embodiment of the present disclosure. On the basis of the foregoing embodiments, the intelligent voice interaction method provided in this embodiment specifically includes the following steps:

Step 801: receiving dot matrix data of each stroke, transmitted by the digitizer tablet, when the user draws on the digitizer tablet.

In this embodiment, the digitizer tablet 11 can further propose a simple drawing task to the user, for example, the digitizer tablet 11 broadcasts that: “Now, let's start drawing a boat.” The user starts drawing on the digitizer tablet 11, and each time a stroke is drawn, the digitized tablet 11 transmits dot matrix data of the stroke to the cloud server 12.

Step 802: determining an object drawn by the user according to the dot matrix data of each stroke when the user draws on the digitizer tablet and an image database of simple drawings.

In this embodiment, the cloud server 12 further stores an image database of simple drawings, which stores images of simple drawings of more than 2000 kinds of objects, for example, images of simple drawings of an object such as a television, an electric fan, a bicycle, or an apple. And each object can have more than 100 images of simple drawings.

After the cloud server 12 receives the dot matrix data of each stroke drawn by the user on the digitizer tablet 11 that is transmitted by the digitizer tablet 11, the cloud server determines an object drawn by the user according to the dot matrix data and the image database of simple drawings.

In an embodiment, the determining an object drawn by the user according to the dot matrix data of each stroke when the user draws on the digitizer tablet and an image database of simple drawings includes: determining a drawing image according to the dot matrix data of each stroke when the user draws on the digitizer tablet; and identifying the drawing image through a neural network model pre-trained by the image database of simple drawings to determine the object drawn by the user.

For example, the cloud server 12 may pre-train the neural network model by using images of simple drawings in the image database of simple drawings to obtain a trained neural network model, where the neural network model may specifically be a deep residual network model. After the cloud server 12 receives the dot matrix data of each stroke drawn by the user on the digitizer tablet 11 that is transmitted by the digitizer tablet 11, the cloud server 12 determines a drawing image formed by the current stroke according to the dot matrix data of each stroke of the user, and identifies the drawing image by using the trained deep residual network model to identify the object drawn by the user.

Step 803: transmitting audio information corresponding to the identification result to the digitizer tablet, enabling the digitizer tablet to play the audio information.

For example, if the cloud server 12 identifies that the object drawn by the user is not a boat but a brick, the cloud server 12 may transmit audio information to the digitizer tablet 11, and the digitizer tablet 11 plays the audio information, for example, the digitizer tablet 11 plays: “I think you are drawing a brick.”

In addition, if the cloud server 12 determines that the object drawn by the user does not conform to the simple drawing task proposed by the digitizer tablet 11 to the user, the cloud server 12 may also transmit an image of a simple drawing that is requested by the digitizer tablet 11 to the user, for example, an image of a simple drawing of a boat, to the digitizer tablet 11, so that the user can re-draw a boat in accordance with the image of the simple drawing of the boat.

If the cloud server 12 identifies that the object drawn by the user is a small boat, the cloud server 12 can transmit audio information to the digitizer tablet 11 to give the user a compliment and start a new task, for example, the digitizer tablet 11 plays: “Good job, the boat you drawn is great. Let's move on to the next one. Let's start drawing a computer.”

In an embodiment, during writing or drawing, the user may also have a voice interaction with the digitizer tablet. For example, the user asks the digitizer tablet: “How is the weather today?” The digitizer tablet can convert the voice signal from the user to an audio signal, and transmits the audio signal to the cloud server, the cloud server acquires weather information of the area to which the digitizer tablet belongs according to positioning information of the digitizer tablet, and transmits the weather information to the digitizer tablet, and the digitizer tablet broadcasts the current weather information in the form of audio playing, that is, the digitizer tablet has a function as a smart speaker. In addition, the digitizer tablet can also transmit characters or drawings input by the user to other terminal devices such as computers, mobile phones, tablets, and the like.

According to the embodiment of the present disclosure, a digitized tablet collects drawing information input by a user, and transmits the drawing information to a cloud server, where the cloud server identifies the drawing information to identify an object drawn by the user and transmits audio information corresponding to an identification result to the digitizer tablet, so that the digitizer tablet plays the audio information, in this way, the digitizer tablet performs an intelligent voice interaction with the user according to the drawing information input by the user when the user draws on the digitized tablet, thus increasing the user's interest in painting.
